An annual plant is a plant that completes its life cycle, from germination to the production of seeds, within one growing season, and then dies. Globally, 6% of all plant species and 15% of herbaceous plants are annuals. Common examples: Petunias, marigolds, zinnias, impatiens
While true annuals do not survive the winter, some popular varieties will magically “come back” because they are prolific self-seeders. Common self-seeders: Sweet alyssum, cosmos, bachelor’s buttons, and sunflowers.
The longest-blooming annual flowers bloom continuously from late spring straight through to the first autumn frost. Top performers include Lantana, Zinnias, Petunias (and their cousin Calibrachoa), Cosmos, and Angelonia. These plants provide non-stop color for 4 to 6 months.
